Download or read book Linear and Nonlinear Optical Properties of Metal Nanoparticles and Nanoparticle-based Assemblies written by Robert Charles Johnson and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of HRS experiments on core-shell nanoparticles, in which a thin layer of a second material is deposited onto a core gold nanoparticle, are also reported. Depending on the identity and thickness of the shell, the gold particle frequency doubling response can be increased or decreased by orders of magnitude.
